pip - how to use it?

[amgp]

Purchased a book on Python Game Programming and got stuck after chapter 1.
At the start of chapter 2 i was told to type in: $pip --version and also $pip install cocos2d
I tried entering both of those commands in Python IDLE, and in the various Python folders using windows command prompt.
In all cases I met with failure.
Any ideas from anyonee?
